Pulse (dynamic flow) chemisorption, conducted at a temperature of interest, can determine the number of accessible active sites, active surface area, degree of dispersion, and active particle (crystallite) size. Pulse chemisorption is commonly used to probe strong active sites only, while the static technique can distinguish between strong or weak active sites.

Zeta Potential is the characterization of the electrokinetic potential of liquid-liquid or solid-liquid colloidal dispersions. At PTL, zeta potential is measured using the Zetasizer Nano ZS (Malvern Instruments), which calculates zeta potential using the principle of electrophoresis.

Light Obscuration, also referred to as Single Particle Optical Sensing (SPOS), is an analytical technique of high resolution capable of detecting a small percentage of outliers. It can also be used to obtain an overall size distribution, when operated with proper technique.

Electric Sensing Zone is also referred to as the Coulter Technique or Coulter Counter. The instrument is a true high resolution, high speed particle counter and particle size distribution analyzer that covers a nominal span of about 1.0 µm to 260 µm.

Differential Scanning Calorimetry (DSC) is the measurement of heat flux with respect to a reference as a function of temperature. The DSC instrument used at Particle Technology Labs is the Netzsch DSC 200 F3 Maia. This instrument has been qualified for use from -170 °C to 600 °C and is capable of taking measurements with just a few milligrams of sample.

The FT4 Powder Rheometer by Freeman Technologies is a universal powder tester which can measure dynamic, bulk, and shear properties, in addition to wall friction measurements. The variety of testing techniques allows for the measurement of a powder in several different powder “states”: dynamic, static or under a stressed condition.

Thermogravimetric Analysis (TGA) involves the determination of the change in mass of a sample as a function of temperature and/or time of heating. The TGA instrument used at Particle Technology Labs is a Netzsch TG 209 F3 Tarsus. This instrument has been qualified for use from ambient temperature to 1000 °C and is capable of taking measurements using just a few milligrams of sample.
